The October, 2008 issue of the journal Diabetes published the outcome of a study of middle-aged men and women which found that lower serum vitamin D levels were associated with an increase in the risk of developing insulin resistance and elevated blood sugar over a ten year follow up period.

Researchers at the Institute of Metabolic Science in Cambridge, England followed 524 nondiabetic participants in the Ely Study, a prospective study established in 1990. Upon enrollment, the vitamin D marker serum 25-hydroxyvitamin D, serum parathyroid hormone, insulin-like growth factor-1 (IGF-1) and other factors were measured, and personal health habits such as smoking status and physical activity levels were ascertained. Weight, height, waist circumference, blood pressure, plasma glucose, lipids, and fasting insulin were measured during the initial and ten year follow-up visits.

At the end of the follow-up period, having a higher serum vitamin D level was associated with a lower adjusted ten-year risk of elevated blood sugar, insulin resistance, and high metabolic syndrome score. An association between increased IGF-1 levels and metabolic syndrome risk observed in an earlier study was not noted in the current research.

In an accompanying editorial, Robert Scragg of the University of Auckland in New Zealand asks the question, “Are we ready for a prevention trial?” In light of the dramatically rising diabetes rates worldwide and the mounting evidence for a role of vitamin D in the prevention of the disease, well-designed clinical trials involving vitamin D supplementation are needed to confirm vitamin D’s possible protective benefits. Dr Scragg notes that the dose of vitamin D administered in these trials needs to be at least 2,000 international units per day in order to raise serum 25-hydroxyvitamin D levels above 80 nanomoles per liter, a level at which diabetes risk is lowest. “If well-designed trials are carried out and confirm a protective effect from vitamin D, it could be used by the general population as a simple and cheap solution to help prevent the diabetes epidemic,” he concludes.

When physicians review a patient’s blood test results, their primary concern is any result that falls outside the normal laboratory reference range. The problem is that standard reference ranges usually represent “average” populations rather than the optimal level required to maintain good health. It now appears that most standard reference ranges are too broad to adequately detect health problems or prescribe appropriate therapy on an individual basis. This is especially true when these reference ranges are relied on to treat a patient with a serious medical disorder.

In addition to these special male and female panels, the following tests are especially important for men and women over age 40: fasting insulin, fibrinogen, thyroid stimulating hormone (TSH), and free triiodothyroxine (T3). If a serious abnormality is detected—such as elevated blood glucose (sugar), hormone imbalance, or high cholesterol—testing should be repeated more often than annually to determine the benefits of any therapy you are using to correct the potentially life-shortening abnormality.

In order for calcium to prevent bone loss, adequate amounts of vitamin D3, zinc, manganese and other nutrients should be available so that calcium, magnesium, and phosphorus can be incorporated into the bone matrix. Another issue that many people are not aware of is that many forms of calcium do not absorb particularly well.

In order to overcome the impediments that preclude aging women and men from achieving optimal calcium status, a mineral formula has been designed that provides 1200 elemental milligrams from three different forms of calcium per daily dose, along with critically important nutrients needed to promote healthy bones. Bone Restore delivers a potent dose of magnesium, along with nutrients that enable calcium and magnesium to be incorporated in the bone matrix, like boron and silicon to further boost the body’s ability to maintain healthy bone density.

Scientists have begun to investigate the ability of certain biological components of whey protein, including lactoferrin, beta-lactoglobulin, alpha-lactalbumin, glycomacropeptide, and immunoglobulins, to enhance immunity. Years of scientific research have resulted in the development of a specially designed whey protein that can boost immune function, protect against free radical attack, and maintain lean muscle mass.

The Enhanced Life Extension Protein supplement contains 100% whey protein isolate plus added lactoferrin. The whey protein isolate is made using a process known as cross flow microfiltration, which produces an isolate that is 90% protein, 99% of it in the bioavailable undenatured form, and retains all important subfractions in their natural ratios. This whey protein isolate contains high amounts of calcium, low amounts of sodium, and added Bioferrin™, which is a 95% pure bioactive form of lactoferrin.
